Abstract

PURPOSE:To prevent a back foot from being damaged when a tile basis is separated from a lower mold in compression molding of a tile with a back foot on the back. CONSTITUTION:The specified divided part 2b of a lower mold 2 which is divided longitudinally is lifted to make an uneven form on the molding surface of the lower mold 2. A molding space enclosed by a frame mold 1, the lower mold 2, and an upper mold 3 is filled with waste soil, and the soil is pressurized to obtain a tile basis T with a back foot t1. While the side of the tile basis T being held by the frame mold 1, the divided part 2b is brought down to separate the part 2b from the recession t2 of the tile basis T. Since no demolding expansion is generated in the tile basis T, the divided part 2b can be separated smoothly without a trouble in which a part of the back foot t1 is broken and left on the lower mold 2. The frame mold 1 is then brought down to remove it from the tile basis T.

As a result of repeated studies of the above-mentioned conventional defects, the present inventor has found that the cause is due to the following circumstances. After the kneaded clay is pressed to form the tile base T as shown in FIG. 6A, when the frame mold 52 is separated from the tile base T as shown in FIG. By releasing the restraint of the side peripheral surface, the compressive stress acting on the tile base T is released, and so-called demolding expansion occurs in the tile base T. Then, as shown in FIG.
Similarly, the back foot t 1 portion of the tile base T also expands, and the protrusion 5 of the lower mold 51 forms the recess t 2 on the back surface of the tile.
3, the back foot t 1 exerts a pressing force.
For this reason, the adhesive strength between the back surface of the tile base T and the lower mold 51 is increased, and when the two are separated, the back foot t 1 is partially damaged.

However, in the present invention, the lower mold is composed of vertically divided parts, all or a part of which can be moved up and down, and a predetermined one of the divided parts is raised to the back surface of the tile. I set up my soles. Then, in demolding the tile base, the raised one of the divided parts is lowered to separate it from the concave part on the back surface of the tile base, and at the same time or after that, separate the frame form from the tile base. did. For this reason, while separating the raised divided portion from the concave portion of the back surface of the tile base, the side peripheral surface is held in a state of being constrained by the frame mold, so demold expansion does not occur in the tile base, Therefore, the adhesive strength between the divided portion and the tile base material does not increase. Therefore, it is possible to smoothly separate the both, and there is no fear that the back foot is damaged.

In order to remove the tile base T obtained in this way, the upper mold 3 is first separated, and then the frame mold 1 is attached to the upper end surface of the supporting portion 40 as shown in FIG. Lower to the abutting position. Then, the lifting piston 41 projecting from the upper end surface of the support portion 40 is pushed down this time, and the fluctuation thereof is changed through the hydraulic pipe 42 to the lifting piston 43.
Then, by projecting from the upper surface of the base 4, the divided portion 2a of the lower mold 2 rises, and the tile base T is lifted. As a result, the divided portion 2b is separated from the concave portion on the back surface of the tile base T.

By the way, in the present embodiment, as in the previous embodiments, the frame 1 is separated from the side peripheral surface of the tile base T, and the divided portion 2b of the lower mold 2 is separated from the back surface of the tile base. However, it is set to end almost at the same time. Therefore, while the divided portion 2b is being separated from the concave portion on the back surface of the tile base material T, the restraint state of the side peripheral surface of the tile base material T by the frame body 1 is held, so that the tile base material T is demolded and expanded. The divided portion 2b can be separated before the occurrence of. Therefore, the separation step is smoothly performed, and there is no fear that the foot of the tile base material T will be damaged.

As is clear from the above description,
The present invention, when pressure-molding a tile having a back foot with unevenness on the back surface, raises the lower mold that forms a recess between the back feet before or at the same time as separating the frame mold from the tile base. The divided part is lowered to separate it from the back surface of the tile base material. That is, since the lower mold division portion is separated from the back surface of the tile base in a state where the mold release is not generated in the tile base, the separation step can be smoothly and easily performed, and therefore,
There is no risk of damage to the soles of the tiles.
